  • Numerical modeling on sediment capture in catch basins

    Catch basins are designed to convey surface runoff into sewer systems. They are also found to be effective in retaining sediments. A number of factors can influence catch basin sediment capture efficiency, such as sediment size distribution, flow hydraulics and catch basin design. To better understand the influence of these factors, numerical simulations using the Eulerian-Lagrangian method ...

  • Sampling, testing and modeling particle size distribution in urban catch basins

    The study analyzed the particle size distribution of particulate matter (PM) retained in two catch basins located, respectively, near a parking lot and a traffic intersection with common high levels of traffic activity. Also, the treatment performance of a filter medium was evaluated by laboratory testing. The experimental treatment results and the field data were then used as inputs to a ...

  • City of Ottawa Tackles System Overflow and Flooding with Tempest Inlet Controls Case Study

    Over the past few decades, rain events throughout North America have become more frequent and substantial. The combination of increased rain and outdated infrastructure has caused many municipality storm sewers and drainage systems to exceed capacity, resulting in flooding and additional expense. To cost-effectively mitigate the problem, municipalities are turning to the use of inlet control ...

  • Porous Bio-Filters - Tools to Fight West Nile Virus

    The year 2002 brought a disturbing upward trend of West Nile Virus cases to the United States, resulting in more than 232 deaths in 2002, just 3 years since first detected within our borders. This virus is carried by mosquitoes, which thrive in pools of stagnant water – large and small. Large bodies of water can be treated rather easily, by adding predators of the larvae, or chemicals. ...

  • Asphaltic Concrete Parking Lot

    As discussed we have prepared a capital cost estimate for the two options to pave Whistler Parking Lot 1; one for paving with an 80 mm asphaltic concrete surface and one with a gravel pave surface based on a total area of 6,400 sq. meters. The cost of the paved parking lot includes an oil water and sediment control device (Vortechnics), several catch basins and associated drainage piping. Good ...

  • Dry cleaning plant: Boston, Massachusetts

    Site Summary Dry cleaning solvents were found in the soil under a parking lot adjacent to a large dry cleaning plant located in a mixed commercial and residential suburb of Boston, Massachusetts. The contamination was traced back to a storm water catch basin in the parking lot which contained sediment and sludge with high concentrations of the dry cleaning solvent perchloroethene (PCE). The ...

  • Wet Prairie Restoration & Created Wetland - Case Study

    ERC was hired by the Columbus & Franklin County Metro Parks to restore approximately 75 acres of wetland habitat within a 150year-old farm field. This project included the installation of sediment & erosion controls followed by an extensive search of the agricultural field for subsurface tile drainage.  This was followed by abandonment of the existing tile network.  Once ...

  • Peach Processing Wastewater Treatment

    A major fresh pack operation of peaches and nectarines needed a screening system to remove the labels and peach fuzz from their wash water before it was pumped from the pond for irrigation use. Flow to the pond is a steady flow of 50 gpm, rising to 600 gpm during periodic draining of the peach coolers and washing systems. The water is a combination of wash water, labels and fuzz from the fruit, ...

  • What is a storm water filtration?

    Water is the main source of living for human beings on this earth. Water is not only essential for human life but also it is a fundamental natural resource for sustaining of wildlife and environment. It is the main substance for surviving a healthy life. There are many vital resources which contaminate the water and many death implications occur. Due to many natural calamities, the water source ...

  • Balancing growth and conservation - Precast concrete manholes become part of the stormwater solution

    When American Fork, Utah, decided to approve construction of a 175-acre commercial center, the city engineers had to consider the environmental effect it would have on a 45-acre wetland right next door. Under the EPA´s Phase II Storm Water Rules, adapted in late 1999, almost any city large enough to require a storm sewer system must balance growth with the environmental impacts of ...

  • Evironmentally Concious Stormwater Management Through Sustainable Design and Best Management Practices

    ABSTRACTBecause development has dramatically altered the hydrologic environment’s sustainability, the Milwaukee Metropolitan Sewerage District (MMSD) is encouraging the use of “green” design through stormwater management BMPs. The MMSD asked Graef, Anhalt, Schloemer and Associates, Inc. (GAS) to evaluate and design stormwater management BMPs. The MMSD headquarters in Milwaukee, WI is serving as ...

  • Fritz Sick Pool Cultec Parking Lot Rehabilitation

    Improper grading in the parking lot of the Fritz Sick Swimming Pool in Lethbridge, Alberta, led to stormwater flooding in the building and breakdown of the lot’s asphalt and subgrade. The consultant and contractor were open to an approach Nilex proposed, based on a complete solution of supply and installation with a rapid turnaround for design. The ability to respond quickly with a solid ...
